Application filed May 2, 1923, Serial No. 636,160. Renewed December 15, 1924.

T 0 all whom it may concern:

Be it known that I, MILTON A. IVAGNER, a citizen of the United States, residing at Glendale, in the county of Douglas and State of Oregon, have invented new and useful Improvements in Undercutting Saw Rests, of which the following is a specification.

This invention relates to new and useful improvements in under-cutting saw rests.

The principal object of this invention is to provide a. simple saw rest which may be attached to a support and one which may be readily moved to suit the convenience of the user.

Another object is to provide a rest of this character which is simple in construction, and therefore cheap to manufacture.

A still further object is to provide a rest 0 which will enable one man to under-cut a log without undue effort upon the operators part.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same- Figure 1 is a cross section taken on the line 1-1 of Figure 2,

Figure 2 is a side elevation of my device mounted upon a suitable support,

Figure 3 is a top plan view of Figure 1,

Figure 4 is a diagrammatic view showing the manner of using my device in connection with the sawing of a log, and

Figure 5 is an end elevation of a log showing my device supporting a saw in under-cutting position.

It often happens that it is easier to saw a log by under-cutting than by sawing clownwardly from the top as the natural weight of the log will cause the under-cut to spread and not pinch the saw as is the case with the upper-cut which necessitates the use of wedges.

I have therefore designed a very simple rest which may be attached to the handle of a woodsmans axe, which rest consists of a clamp having a roller pivotally mounted thereon, this roller having a. groove within which the back of the saw is adapted to be moved.

In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention the numeral 5 designates a log, while the numeral 6 designates the head of an axe, while the numeral 7 refers to the straight handle of the axe. It is obvious that other forms of axes may be used but I prefer the woodsmans axe having the straight handle.

At 8 I have shown a substantially semicircular member to which is pivoted at 9 a second semi-circular member 11. These two members form a clamp which is adapted to contact the handle 7 of the axe. Pivoted at 12 is a lever 13 having a link 14 secured thereto. The opposite end of this link is adapted to be engaged in notches 16 formed in the free end of the semi-circular memher 8.

Mounted upon the semi-circular member 8 is a yoke 17 within which a wheel 18 is freely rotatable. This wheel 18 is grooved so as to receive the back of a saw 19.

The operation of my device is as follows The axe is swung so that the head 6 is firmly embedded in the log to be sawed as indicated in Figures 4 and 5. My clamp is then opened by swinging the parts to the position shown in dotted lines in Figure l, and then placing the same around the handle 7 of the axe after which the clamp is adjusted as shown in full lines in Figure 1, after which the device is ready for use. The saw is now laid upon the roller so that the teeth of the same engage the undersidc of the saw which is then recipro'cated in the usual manner.

It will thus be seen that I have provided a very simple yet efficient device which will perform all of the objects set forth.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, I claim In a device of the character described, a substantially semi-circular member, a second substantially semi-circular member pivoted to said first member, a lever pivoted to the free end of said second mentioned member, a link pivoted to said lever, and adapted to engage notches formed in the free end of said first mentioned semi-circular member in such a manner that said link will lie off center so as to cause said lever to contact the curved portion of said second mentioned In testimony whereof I aflix my signature.

MILTON A. VAGNER.
